Short description
Fossil crocodile dorsal vertebra, reconstructed to approximate shape in life
Full description
Bar at the bottom is 6 cm long. The centrum was not modified. The left postzygapophysis (pzo) was broken during burial and ended up stuck onto the top of the right neural arch, so the part of the mesh for this left pzo was plucked off the right neural arch and placed on the left neural arch in a position matching the right pzo, after it was lifted up from its distorted downward attitude. Green colored parts of the mesh show areas of the mesh that were created through stretching of distorted or broken areas to better align broken edges.

Description
Moved the left postzygapophysis (pzo) from the right neural arch, where it was moved during burial, and reshaped right postzygapophysis (pzo) to approximate life attitude.

Processing Activity 2:

Software
Modo
Description
Colored the parts of the mesh added through stretching the right postzygapophyis into approximate life attitude, and also colored other parts of the mesh where some repositioning was done.
